How to Use the Timecard Calculator
- Enter Clock In/Out Times – Use the time inputs (HH:MM format, 24-hour). Defaults are 09:00 and 17:00.
- Set Break Duration – Enter break time in minutes (default 30). Must be 0 or more.
- Input Hourly Rate – Your pay per hour in dollars (default $20). Cannot be negative.
- Adjust Overtime Settings – Set the daily overtime threshold (default 8 hours) and the overtime rate multiplier (default 1.5x). Multiplier must be at least 1.
- Enter Tax Rate – Percentage (0–100) for deductions (default 20%).
- Click “Calculate” – Results show: Total Hours, Regular Hours, Overtime Hours, Gross Pay, Tax Deduction, and Net Pay.
Key Rules:
- Clock Out must be after Clock In.
- Total work time (after break) must be positive.
- All fields require valid numbers.
Formula Summary: Total Hours = (Clock Out – Clock In) – Break; Regular Hours = min(Total, Threshold); Overtime = max(0, Total – Threshold); Gross = Regular × Rate + Overtime × Rate × Multiplier; Net = Gross × (1 – Tax/100).

Frequently Asked Questions
Overtime is calculated as hours worked beyond the overtime threshold per day, multiplied by the overtime rate multiplier. For example, if you work 10 hours with an 8-hour threshold and 1.5x multiplier, you get 2 overtime hours paid at 1.5 times your hourly rate.
This calculator is designed for a single day's timecard. For multiple days, you would need to calculate each day separately and sum the results.
Set the break duration to 0 minutes. The calculator will not deduct any break time.
